This work-package will be dedicated to the management of the overall project, technical coordination of the RTD activities/work-packages as well as administrative management for which ALMA has excellent demonstrated experience.
Objectives: to promote transfer of knowledge, training and networking integration of different research group and professionals, and to increase engineers and researcher’s qualification and skills.
Description: training and networking activities will take place trough specific summer schools and trough secondment of the personnel in different premises during the project life time.
Objective: to promote dissemination of project results and exploitation of the project achievement to maximize the impact of the project results.
Description: In this WP a deep review of the target telecommunication sector of the technology developed will be done. The most promising field of application (e.g. navigation antennas, Ku/Ka ground to satellite communication antenna etc.) of growing potential and societal potential will be identified and a feasibility study regarding the impact of this new technology on these specific issues will be performed.
The whole results of the project will be disseminated to the general public.
Objectives: To design and simulate different topologies of antenna based on plasma elements.
Description: The expertise and experience acquired from the theoretical analysis of WP1 and WP3 along with the simulation results of WP2 will be exploited and blended together in order to conduct a series of comprehensive multi-parametric simulations for the design of optimized antenna elements. The designed plasma-element antennas will be assessed versus current metallic antennas in terms of performance.
Objective: To design, develop and test a demonstrator based on the achievement of WP2 and WP3.
Description: The code developed in WP2 and the technology developed in WP3 will be combined to develop a prototype demonstrator based the more promising technology (Hollow cathode or aluminosilicate inorganic polymers). The design will be targeted to an application identified in the frame of WP6 exploitation plan). Sources will be built and extensively tested.
Objective: This WP will be focused on solving the technology challenges involved in the design and development of sources based on hybrid technology.
Description: The plasma source material will be based on low –work function materials. The basic material will come from existing hollow cathode technology and will be fully analysed, moreover advanced materials will include, aluminosilicate inorganic polymers specifically manufactured to achieve non- isotropic properties. Different layouts of RF antennas will be tested in combination with different materials of the source. The best manufacturing technology for the plasma source as well as Additive Manufacturing Technology will be considered to obtain sophisticated plasma sources with complex geometry will be also investigated.
Objectives: To develop new numerical tools to support the physical investigations and design of advanced plasma sources.
Description: The code based on Particle In Cell (PIC) algorithm which is currently used in combination with an electromagnetic solver will be combined with a fluid code.
The fluid code will be used to simulate the whole plasma evolution (high density) whilst the PIC code will be used to simulate local phenomena. Both codes will be upgraded with physical models identified in WP1. Code will be validated using the experimental set-up of WP1.
Main objective: To build up physical models suitable to study the main physic aspects behind the hybrid sources.
Description: This work package will be focused on performing a basic physics investigation into the most relevant physical phenomena involved in hybrid plasma sources. Two plasma sources having different operational parameters will be developed using materials coming from hollow cathode and Radio frequency excitation. These sources will be instrumented and will undergo a deep experimental campaign to characterize power absorption, plasma evolution, and plasma uniformity, as function of experimental conditions. Theoretical models will be identified to model: (i) plasma wave interaction in the bulk and in the sheath region, (ii) transport phenomena, (iii) nonlinear phenomena.
